Thread: Advert Layout
22/12/2009 11:54:09
I also have Computeractive and Webuser, both same Publisher and they have adopted the annoying practice of full page advert one side and full page Editorial on the other side. At one time they printed ads on both sides of a page + I just ripped them out, now I`m snookered!
I do tend to read an article, turning the page to find where its continued and ignore the ad. in between.

Thread: Iron Castings
14/12/2009 10:12:24
I live in Brighton, so looking local, say Sussex/Hants/Kent/Surrey.
I want 2 off, Iron Castings from one pattern about 9" long.
Problem is finding suitable Iron Foundry.
Can anyone help, please?

Thread: Citric acid as pickle
14/12/2009 09:21:14
Circlip and everyone,
Sorry I forgot to mention that  all acids are neutralised by alkalies and vice versa. Just use a strong one  to kill the other strong one e.g., Caustic Soda to kill Sulph. Acid, or other way round.

Hi Circlip,
A fellow model engineer once showed me his Sulph. Acid pikling tub 4 small items - washing-up bowl under the bench, which after long use, developed large brown objects that looked like sea anemones. He said they had grown in the acid but I dont know whether this was a leg-pull or not.
As regards clothes that are more hol(l)y than righteous, Sulph. will dry out whitish but when next wetted, comes alive again and starts attacking cloth, skin, wood or I suppose, anything organic. The stuff is very difficult to eradicate.
Take Care!
John.
Thread: Fluxes

Hullo Dunstan,
I expect that retailers trying to rubbish Borax in favour of newer chemicals, which of course they stock, have a vested interest in flogging their more expensive "superior" jollops! Borax + "town Gas" worked well enough for me in school metalwork!

Thread: Finishing a casting
09/12/2009 12:52:11
Hullo John,
I have used `LOY` sometime ago. I seem to remember that it came in squeezy tube, like toothpaste. Got it from carspares shop who were at that time next door to long-gone Blabers Foundry, in Brighton. They recommended the stuff, saying that was what Blabers bought to fill in blemishes in patterns. Try reading up the excellent  description of working on castings at the start of the QUORN articles.

Thread: 2010 Harrogate Show
08/12/2009 09:31:36
Talking about getting directions from mapping websites, first time I went to Bristol xbn., the map showed a big X to indicate target but when I got there I found the toe-rags had sent me to the Health Centre @ other end of town instead of Leisure Centre!! Xbn sites seem to be quite hard to find unless you get the name of road or postcode/zip.Have been to certain xbns so many times, dont need maps any more!

Hi Geoff
To help u find it easily on mapquest or similar, its in Railway Road, just outside of and to South of Harrogate.
Very well worth seeing. I have been 4 a number of years but didnt manage it this year and probably not in 2010 either.
Bristol xbn in Aug and Guildford in July, equally good.

Thread: How many Boiler makers?
06/12/2009 14:56:56
I remember an ME exhibition some years ago, where there was a stand occupied by, I think, a company based in Manchester, demonstrating small (1 1/2"? square ) pure white cubes for insulation whilst boiler-making. They were using a propane burner to show how very little heat was going into their blocks. Seem to recall they were quite expensive, but apparently very effective. 
Perhaps someone may know mor and suggest a supplier?

Thread: Metric vs Imperial - Practical or Traditional?
11/11/2009 11:58:02
I also suffered being taught irrelevant historical measurments like rods poles perches.
Also, decimetres hectometres and so on. Then there was our historic money  with farthings threpenny-joeies, guineas, tanners and so on.
How much easier is the new currency to add, divide and multiply.
The same goes for metric e.g.,  we seem to be using only mm, cm and M, having apparently cut out all the in - between ones like decimetres. Pity 600mm has to be used for kitchen cupboards instead of .6M  Its all about visualising, like Ian said 18,288mm. Why not  make it simpler by saying 18.288M then mentally add on another 10% (1 .8) and you have near enough, 20 (yards!) I am making a Harold Hall design to his metric drawing which uses piece of metal 70 mm long; no prob. visualising this. Equally, I can look for a piece of stock thats around 3 ins. long for it. Most people have digi-calipers and/or DROs, so whats prob? Just seems like something to moan about.

Thread: MT sleeve taper converters
14/10/2009 10:09:13
I need a plain external shank with an internal 1 MT taper. 
Is there such a thing available as a commercial item and does any one have one they would sell/give away? I live in Brighton.
